Let’s face it: if this guy was at all business savey, he would never have accused you of switching the hatchlings in the first place. Even if he believes that a customer has cheated him, he’s stupid to e-mail them on it! (Telephone them, maybe, but you don’t leave a paper trail!) The customer is always right…He’s not even smart enough to completely change his user name to escape the bad feedback. Sheesh!
